3 HYDRAULIC INTEGRATED CIRCUITS General Information Fluid:best use mineral oil with viscosity ranging between 10 and 200 cst. Filter:dirty oil is the main reason for failure and troubles of hydraulic parts and systems. The table below contains OLEOSTAR S.p.A. recommendations about the minimum oil contamination level according to individual specifications of different items. For further safety of your hydraulic equipment and of all valves assembled on it, we either recommend use suction filters (rather than return filters) or separated filter lines. TYPE OF EQUIPMENT - TYPE OF VALVE - Heavy duty equipment - Equipment running at bar ( psi) working pressure - Equipment using proportional controls - Equipment with high frequency cycles - Equipment running up to 210 bar (3050 psi) working pressure - Spool-type valves - Valves with calibrated ports - Equipment running at low working pressure - Pilot plants and equipment - Equipment with low frequency cycles CONTAMINATION LEVEL According to ISO /16/13 -/18/14 -/19/15 Installation:make sure to provide suitable gasket lubrication with clean oil before screwing the cartridge on the valve body. Also make sure to screw the cartridge manually in to reach against the gaskets in the valve body. Material:internal components made out of high grade steel duly treated and fabricated. For more information please ask our technical office. Working temperature:min. -25 C (-13 F) max. 90 C (194 F) with standard BUNA N seals. min. -20 C (-4 F) max. 200 C (392 F) with optional VITON seals. Rating diagrams:all rating diagrams of this catalogue are measured with mineral oil of 46 cst viscosity at 40 (104 F) temperature. All drawings dimensions are defined as mm in

13 ELECTRIC COILS FOR TUBES Coils BE and BT Operation Multiple coil versions are available to allow use with direct and alternated current. Thermal insulation class: F (Tmax = 155 C-303 F-) (VDE 0580) Relative duty cycle: ED 100% (VDE 0580) To assure ED = 100% and perform continuous coil operation, the following conditions should be met: TA + T < Tmax Whereas: -TA = ambient temperature - T = temperature increase due to operation -Tmax = maximum admissible temperature according to insulation class We therefore recommend always checking that the maximum ambient temperature is same as Tmax - T (providing no special operating requirement are there). Safety standards (DIN 40050):IP54 without connector IP65 with connector Admissible voltage range for long lasting and trouble free operations life: nominal voltage ±10% Performance Resistance Ω Current (A) Power (W) or (VA) T Type T A =20 C 68 F Cold Warm Cold After 1 hour at: -Ta=20-25 C F -Nominal voltage BE 12 Vcc 7,7 1,56 1,16 18,7 W BE 24 Vcc 31 0,77 0,58 18,6 W BE 48 Vcc 116 0,41 0,3 19,8 W BE 110 Vcc 700 0,157 0,12 17,3 W BE 24 Vca (50 Hz) 5,3 1,16 0,87 28 VA BE 48 Vca (50 Hz) 21,3 0,6 0,45 28,8 VA BE 110 Vca (50 Hz) 108 0,26 0,19 28,6 VA BE 220 Vca (50 Hz) 438 0,13 0,09 28,6 VA BE 380 Vca (50 Hz) ,09 0,06 34,2 VA BE 24 RAC 27 0,8 0,6 17,3 W BE 110 RAC 630 0,157 0,12 15,6 W BE 220 RAC ,08 0,06 15,7 W BT 12 Vcc 6,8 1,77 1,15 21 W - - BT 24 Vcc 27 0,89 0,58 21 W - - BT 48 Vcc 110 0,43 0,32 20,3 W BT 110 Vcc 700 0,15 0,11 15,7 W BT 24 Vca (50 Hz) 4,2 0,94 0,83 22,6 VA - - BT 48 Vca (50 Hz) 15,3 0,73 0,54 35 VA BT 110 Vca (50 Hz) 89 0,21 0,18 23,1 VA - - BT 220 Vca (50 Hz) 350 0,1 0,08 22 VA - - BT 24 RAC 90 0,47 0,37 20,7 W BT 110 RAC 540 0,2 0,16 21,6 W BT 220 RAC ,1 0,08 21,7 W (C ) (F ) 13

16 Solenoid connectors CC-CA, CL and CP CONNECTORS Operation There are 3 types of different solenoid connectors: CC-CA 2-poles + GROUND electric connectors in compliance with DIN and A/ISO standards and Electric connectors suitable for connection of DC and AC current coils. Type of current must be same as for the coil used. CL 2-poles + rectifier + GROUND electric connectors in compliance with DIN and A/ISO standards and Electric connectors suitable for connection of DC current coils BE RAC. AC current operation only. Use of these poles depends on the type of valve used. CP 2-poles + rectifier + GROUND electric connectors in compliance with DIN and A/ISO standards and Electric connectors suitable for connection of DC current coils BT RAC. AC current operation only. Use of these poles depends on the type of valve used.
